Many idealizations and ideal conditions in physics have been an important role in understanding of the basic physics concepts and in solving physics problems. The purpose of this study was to explore the relationships of pre-service teachers' misconception of heat with their understanding of the ideal conditions involved in solving problems of heat and temperature. Test instruments were composed of two parts. One part was asked to answer the heat conceptions, the other to write statements in relations to ideal condition hidden in the process of heat problems solving. For this study, pre-service teachers who are in four major courses in the University of Education in a local city were selected and total numbers of pre-service teachers were 108 students. The framework was developed for classifying pre-service teachers response of open items of ideal conditions of heat domains. According to the framework, each types of response were coded, analyzed and processed with a SPSS/PC program. The results are as the followings. In the heat conceptions, most of students showed correct response, and there was no significant differences between major courses. In understanding of ideal conditions, students' responses of "idealized condition relevant to problem" showed 65.2％ of them, and "not relevant idealized conditions" 15.5％, and no response 12.2%. In the 15.5% of students "not relevant idealized conditions", 10.5％ of them did not explained correctly conditions, just simply 2.7％ stated the laws in physics or formula, 1.6% generally, but irrelevantly described the idealized conditions. More importantly pre-service teachers showed very weak correlation between heat conception and understanding of ideal condition. Although we concluded there were no significant relationships of heat conception in understanding of ideal conditions in thermodynamics domain, these suggest that many other factors may influence understanding of ideal conditions in physics.

Periodontal inflammation increases the risk of tooth loss, particularly in cases where there is an associated loss of alveolar bone and periodontal ligament (PDL). Histological and morphometric evaluation of periodontal inflammation is difficult. Especially, the lengths of the periodontal ligament and interdental alveolar bone space have not been quantified. A quantitative imaging procedure applicable to an animal model would be an important clinical study. The purpose of this study was to quantify the loss of alveolar bone and periodontal ligament by evaluation with micro-computed tomography (micro-CT). Another purpose was to investigate differences in infections with systemic E. coli LPS and TNF-${\alpha}$ on E. coli lipopolysaccharide (LPS) in loss of alveolar bone and periodontal ligament model on mice. This study showed that linear measurements of alveolar bone loss were represented with an increasing trend of the periodontal ligament length and interdental alveolar process space. The effects of systemic E. coli LPS and TNF-${\alpha}$ on an E. coli LPS-induced periodontitis mice model were investigated in this research. Loss of periodontal ligament and alveolar bone were evaluated by micro-computed tomography (micro-CT) and calculated by the two- and three dimensional microstructure morphometric parameters. Also, there was a significantly increasing trend of the interdental alveolar process space in E. coli LPS and TNF-${\alpha}$ on E. coli LPS compared to PBS. And E. coli LPS and TNF-${\alpha}$ on E. coli LPS had a slightly increasing trend of the periodontal ligament length. The increasing trend of TNF-${\alpha}$ on the LPS-induced mice model in this experiment supports the previous studies on the contribution of periodontal diseases in the pathogenesis of systemic diseases. Also, our findings offer a unique model for the study of the role of LPS-induced TNF-${\alpha}$ in systemic and chronic local inflammatory processes and inflammatory diseases. In this study, we performed rapidly quantification of the periodontal inflammatory processes and periodontal bone loss using micro-computed tomography (micro-CT) in mice.

The purpose of this study was to examine the relationship between job stress, turnover intention, and the moderating roles of motivation for child care work. The subjects were 238 child-care teachers who were worked at child-care centers in Seoul. Questionnaires were used to rate job stress, turnover intention, and the motivation for child care work of teachers. The collected data were mainly analyzed by descriptive statistics, t-test, one-way ANOVA, Duncan test, Pearson's correlation and the multiple regression analysis. The main results of this study were as follows. First, there were differences in turnover intention according to individual characteristics such as career at the current child-care center and total career. Second, job stress was positively correlated with turnover intention, and negatively correlated with active motivation and material motivation. And turnover intention was negatively correlated with active motivation and material motivation. Third, a moderator effect of the active motivation was found in the relationship between the job stress and the turnover intention. Especially the active motivation is suggested to reduce the negative results of job stress and turnover intention. Therefore, the results indicate the importance of the active motivation which is considered as an aptitude, interest, affection for children and self realization when child-care teachers make a decision to enter the child-care work profession.

This study examines the meaning of classical texts in contemporary society. Drawing on an anthropological investigation of Somun Hakhoe, an association of Korean medicine doctors in South Korea, and its foundational text "Somun Daeyo", the present study explores the interconnectedness of medical texts and medico-social practices in bringing medical tradition into the contemporary era. The themes that author Lee Kyu-joon emphasizes in "Somun Daeyo" are thoroughly embodied in Somun Hakhoe's medico-social practices, such as the study activities based on "Somun Daeyo"(in particular, on Somun Buseol, the five articles written by the author, attached to "Somun Daeyo"), the focus on Buyang theory(扶陽論), and the distinctive feature of composing formula. The ethnographic data collected about the group activities of Somun Hakhoe also demonstrate that the social relationship of the teacher and disciples plays an important role in bringing East Asian medicine into the present. This study articulates the significance of the interaction between the classical text and the medico-social practices around it. The dynamism taking place in the interaction points to the "living tradition" actively flowing rather than being static in the past. This study illustrates the close relationship between medical history and medical anthropology and encourages more studies of classical texts based on the intimate relationship between the two disciplines.

This study aims to find the method to promote interaction in L2 classrooms. Active interaction between learner-to-learner and learner-to-teacher in L2 classroom plays an important role in language acquisition. In light of this, L2 classroom would benefit with the help of learning tools such as Clickers which helps learners to express their level of understanding during the process of learning itself. This is because the anonymity of Clickers allows learners to express their needs without the social risks associated with speaking up in the class. It allows for an evaluative feedback loop where both learners and teachers understand the level of progress of the learners, better enabling classrooms to adapt to the learners' needs. Eventually this tool promotes participation from learners, This is in turn, believed to be effective in fostering classroom interaction, allowing learning to take place in a more comfortable yet vibrant way. This study is finalized by presenting the result of an experiment conducted to verify the effectiveness of this approach when teaching pragmatic aspect of the Korean expressions with similar semantic functions. As a result of the research, the learning achievement of learners in the experimental group was found higher than the learners' in a control group. Analyzing the data collected from a questionnaire given to the learners, the study presented data suggesting that this approach increased the scope of interactivity in the classroom, thus enhancing more active participation among learners. This active participation in turn led to a marked improvement in their communicative abilities.

Purpose: Although medical curricula are now better structured for integration of biomedical sciences and clinical training, most teaching and learning activities still follow the older teacher-centric discipline-specific formats. A newer pedagogical approach, known as Collaborative Learning Cases (CLCs), was adopted in the medical school to facilitate integration and collaborative learning. Before incorporating CLCs into the curriculum of year 1 students, two pilot runs using the action research method was carried out to improve the design of CLCs. Methods: We employed the four-phase Kemmis and McTaggart's action research spiral in two cycles to improve the design of CLCs. A class of 300 first-year medical students (for both cycles), 11 tutors (first cycle), and 16 tutors (second cycle) were involved in this research. Data was collected using the 5-points Likert scale survey, open-ended questionnaire, and observation. Results: From the data collected, we learned that more effort was required to train the tutors to understand the principles of CLCs and their role in the CLCs sessions. Although action research enables the faculty to improve the design of CLCs, finding the right technology tools to support collaboration and enhance learning during the CLCs remains a challenge. Conclusion: The two cycles of action research was effective in helping us design a better learning environment during the CLCs by clarifying tutors' roles, improving group and time management, and meaningful use of technology.

A forecast foresight of the conditions for the development of educational affairs in the Information Society of Ukraine is presented, taking into account changes in the technique, technologies, and the socio-social sphere. Unresolved problems in Ukraine regarding the modernization and improvement of the education system by means of informatization are highlighted. The need for further improvement of Ukrainian education by means of informatization is noted. Formulated the main goal of future education. The necessary conditions for the successful development of future education are highlighted. The role and place of the key figure of the teacher in the education of the future is determined. The article highlights the theoretical and philosophical foundations of professional subjectivity of the future specialist. Recently, the world's pedagogical thought has increasingly focused on how to build an educational process so that it brings a sense of happiness to all its participants. It is believed that this is a new management philosophy in general, although its origins are in ancient Greek sources, which claim that only a happy life has meaning and value. It is found out that the professional subjectivity of a specialist is an important professionally significant quality of the individual, which provides a purposeful and optimal implementation of their mental, personal resources for solving professional and life problems, which is manifested in the desire for self-definition, self-determination, self-regulation and self-improvement in professional activities taking into account the information society. The structure of this phenomenon is shown.
